The XRAY 352289 Composite C-Hub with a 6-degree caster angle is purpose-built for GT on-road racing demands. Extensive angle testing identified 6 degrees as the balance point for sharp steering and reduced tyre degradation. Compatible with GTX and GTXE cars, this hub is a useful change for racers wanting more predictable handling across race distances.
Moving from a 16-degree layout to the 6-degree C-hub changes steering geometry to improve front tyre contact during turn-in. Drivers will notice better directional control when pushing hard through corners.
The lower caster angle helps limit uneven tyre wear, so grip drops off more slowly during long runs. That steadier behaviour supports more consistent lap pacing in endurance formats.
